Can a phone app keep heart patients moving?
NCT ID NCT05643976
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a digital app called KardioPAC could help people in cardiac rehab stay more active and feel better. 43 heart patients used the app alongside standard rehab, or just standard rehab alone. The goal was to see if the app improved exercise habits, blood pressure, and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KardioPAC mobile application (a digital tool for remote monitoring and reminders)
- What this could lead to
- If it works, this could point toward a simple digital tool that helps heart patients stick with exercise and feel better during rehab.
- What could go wrong
- This was a very small, early study (43 people) with no blinding, so results may not apply widely. The app's benefits over standard care are uncertain.
